Place beans in a large pot. Pour in water to cover by 4". Let soak overnight at room temperature.

Drain beans; rinse and return to pot. Pour in water to cover beans by 2". Add celery, carrot, and onion. Bring to a boil. Reduce heat to low; simmer gently until beans are tender, about 1 hour (keep at a gentle simmer or beans will get mushy and split). Discard vegetables; drain beans. Let cool.

Whisk oil and vinegar in a small bowl; season with salt and pepper. DO AHEAD: Beans and vinaigrette can be made 2 hours ahead. Let stand at room temperature.

Transfer beans to a large bowl. Add herbs and drizzle with vinaigrette; toss to coat. Season to taste with salt and pepper.
